You were the bestfriends of the Weasley Twins since your first year, you were the older sister of Harry Potter. You loved pranks so much, that's why you, Fred Weasley and George Weasley were the Prankster Trio since first year and you were now in seventh year.

Since a new teacher was now there and ruining all the mood in the usual chaotic and fun Hogwarts, you all decided to have a new teacher for all the students, but it was a student, and this student was Harry, your brother, who was in fifth year and a really good teacher, much more fun than Umbridge, she was boring.

You were all in the Room Of Requirement, learning some spells while Harry told Ron and Hermione to do a little duel. You were standing next to the Twins as they make a bet on who will win, Fred bet on Hermione and George on Ron, since Hermione was a smart girl she would win for sure.

Of course, in only one hit of spell, Hermione sent Ron flying on the ground, grunting when his back hit the floor, which was quite painful. George gave the galleons to Fred who put them in his back pocket.

"Thaank you."

Fred said, drawing the 'a' a bit to show how proud he was that he won the bet, while George still looked at Ron while answering.

"Shut up..."

George said in a whisper to Fred as they both watched Ron walking toward you three, a bit embarassed.

"I let her do that..."

Ron lied, trying to appear confident, but truly, he was just a loser with spells and Fred nodded like he believed him, crossing his arms.

"It's good manners, isn't it...?"

Ron asked, not expecting a answer, of course he was a embarassed because everyone saw that and some laughed while Hermione was smiling. Fred nodded again toward Ron like he was approving as he look at Hermione. Fred, you and George knew Ron was lying.
